I just finish watching it a few days ago. It is almost true to original comic version. I know a lot of people does not like this comic. But i read this like almost every day when i was a kid. So sad when my comic got trashed by termites. There is another few more powerful stuff that is not mentioned. Like Veil of Vishanti. Eye of Agamoto already shown.

Baron Mordo is supposed to be a fatter mongolian looking guy. Ancient one is supposed to look like those a shaolin monk. In the comics Dr Strange also call on Dormammu to defeat some more stronger beings.
